[Glaucoma and ultrasound biomicroscopy].

Ultrasound biomicroscopy (UBM) can provide high-resolution images in the living human eye; this resolution has been compared to microscopic resolution. This system is particularly useful in studying the anterior segment and analyzing the different types of glaucoma. Anatomical aspects, physiopathological processes and surgical results in glaucoma could be evaluated with UBM. This exploration is also important in determining differential diagnosis, risk factors, and prognostic elements. In addition, using UBM after filtering surgery helps detect early complications and understand poor surgical outcome.
